Ansible ad-hoc
什么是ad-hoc？
ad-hoc简而言之就是“临时命令”，执行完即结束，并不会保存
ad-hoc模式的使用场景
比如在多台机器上查看某个进程是否启动，或拷贝指定文件到本地，等等
ad-hoc模式的命令使用

ad-hoc结果返回颜色
绿色: 代表被管理端主机没有被修改
黄色: 代表被管理端主机发现变更
红色: 代表出现了故障，注意查看提示

command
# 默认模块, 执行命令[root@m01 ~]# ansible web_group -a "hostname"
shell
# 如果需要一些管道操作，则使用shell[root@m01 ~]# ansible web_group -m shell -a "ps -ef|grep nginx" -f 50
script
# 编写脚本[root@m01 ~]# vim /root/yum.sh#!/usr/bin/bashyum install -y vsftpd#在本地运行模块，等同于在远程执行，不需要将脚本文件进行推送目标主机执行[root@m01 ~]# ansible web_group -m script -a "/root/yum.sh"

Ansible主机信息模块
为什么要讲这个模块？
做过自动化的小伙伴会觉得这个模块非常实用
在公司中总会有一些需求
比如：
1.根据不同主机不同IP创建对应IP的目录
2.根据不同主机不同主机名创建对应主机名的目录
3.自动化运维平台需要自动获取到主机的IP地址，内存信息，磁盘信息，主机名...等
4.如果安装数据库，分配内存为物理内存的80%，此时有3台不同物理内存的机器2G、4G、16G
写一个playbook的情况下，我需要获取到对应主机的内存并作出计算，写判断。
setup
1.查看所有详细信息
